**Reflection of Instruction**

At first, students understood the concept of PEMDAS. They understood that you should follow the
steps in that order. What threw them off
was that multiplication and division go from left to right, and addition and
subtraction go left to right when in the same problem. I provided some examples to show that
students would get different answers if they didn’t go from left to right. They could pick up that the answers would be
different, but I still don’t think that students understood why. They didn’t fully grasp the concept of going
left to right.

I understand the confusion, because I experienced the same
confusion when I was younger. In fact, I
don’t think I was properly taught the order of operations in grade school. I was taught PEMDAS, but I don’t believe I
was ever taught that multiplication/division and addition/subtraction go
together from left to right. In result, I was solving problems wrong for
years. This is why I wanted to address
this misconception this early. Students
may not encounter these types of problems on their homework or tests, but they
need to know it for down the road.

I will want to revisit the order of operations again. They will have extra practice between
homework and class time over the course of the next few days.

On a side note, students really enjoyed the PEMDAS
Shuffle. The dance moves helped them use
their whole brain, and gave them a way to remember PEMDAS.
